T In the patentfabove identified ajclutch ofjI this type has been described and claimed.-

As the result of aseries-jof experiments -it Vhas been found that` the clutchfshoy'vn and claimed in the above patentcan be improved vby'making certain changes inthe construcv tion and it is for the purpose/of obtaining protection for .this improvedconstruction that this application is filed.

Y n order to describe our invention so that' its construction and operation can be clearly understood, We shall have reference to the accompanying drawing in vWhich the present preferred embodiment "of the Ainvention shown and inV 'Whichz' 'Fig. 1 is a diametricalfsectiontalen onr Fig. `2 1s a section 'takenon line"2%2,'n
